Barack Obama is on a roll. He has now won 10 states in a row and swept the entire month of February. It has now become the accepted consensus among political commentators and observers that Ohio and Texas are must wins for Hillary Clinton. If she loses either one, the nomination will be over, and all trends are moving in Obama's direction in Texas. But first, here are the results from this week's primaries:

Wisconsin	Votes	%	Del.	Reporting
Obama	646,007	58%	42	100% reporting
Clinton	452,795	41%	32

		Hawaii	Votes	%	Del.	Reporting
		Obama	28,347	76%	14	100% reporting
		Clinton	8,835	24%	6

On the heels these victories, Obama's poll numbers in Texas and Ohio are increasing dramatically. But, for the sake of this post, let's focus on Texas, where he has the best shot at a Hillary upset. Earlier this week, CNN reported a dead heat between Clinton and Obama in the lone star state:

A new CNN/Opinion Research Corp. poll suggests the battle for the Democratic presidential nomination between Sens. Hillary Clinton of New York and Barack Obama of Illinois is a statistical dead heat in Texas, which holds primaries March 4.

In the survey, out Monday, 50 percent of likely Democratic primary voters support Clinton as their choice for the party's nominee, with 48 percent backing Obama.

But taking into account the poll's sampling error of plus or minus 4½ percentage points for Democratic respondents, the race is a virtual tie.
